Various studies have suggested the efficacy of FK-506 in the treatment of a number of ailments, including rheumatoid arthitis (C. Arita, et al., Clincial exp. Immunol.. 1990, 82, 456-461; N. Inamura, et al., Clin. Immunol. Immunopathol. 1988, 46, 82-90), recent-onset diabetes (N. Murase, et al, Diabetes. 1990, 39, 1584-86; N. Murase, et al, Lancet. 1990, 336, 373-74), posterior uveitis (H. Kawashima, Invest. Ophthalmul. Vis. Sci.. 1988, 29, 1265- 71), hepatic injury associated with ischemia (M. Sakr, et al., Life Sci.. 1990, 47, 687-91) allergic encephalomyelitis (K, Deguchi, et al., Brain Nerve. 1990, 42, 391-97), glomerulonephritis (J. McCauley, et al, Lancet. 1990, 335. 674), systemic lupus erythematosus (K. Takabayashi, et al., Clin. Immunol. Immunopathol.. 1989, 51, 110-117), multidrug resistance (M. Naito, et al, Cancer Chemother. Pharmacol.. 1992, 29, 195-200), inflammation of mucosa and blood vessels (PCT Publication WO 91/17754). cytomegalovirus infection (UK Publication GB 2.247.620A). and idiopathic thrombocytopenic purpura and Basedow's disease (PCT Publication WO 91/19495). BACKGROUND OF THE INVENTION Immunoregulatory abnormalities have been shown to exist in a wide variety of "autoimmune" and chronic inflammatory diseases, including systemic lupus erythematosis, chronic rheumatoid arthritis, type 1 diabetes mellitus, type 2 adult onset diabetes, inflammatory bowel disease, biliary cirrhosis, uveitis, multiple sclerosis and other disorders such as Crohn's disease, ulcerative colitis, bullous pemphigoid, sarcoidosis, psoriasis, ichthyosis, and Graves ophthalmopathy. Although the underlying pathogenesis of each of these conditions may be quite different, they have in common the appearance of a variety of autoantibodies and self -reactive lymphocytes. Such self -reactivity may be due, in part, to a loss of the homeostatic controls under which the normal immune system operates. Similarly, following a bone-marrow or an organ transplantation, the host lymphocytes recognize the foreign tissue antigens and begin to produce antibodies which lead to graft rejection. One end result of an autoimmune or a rejection process is tissue destruction caused by mflammatory cells and the mediators they release. Antiinflammatory agents such as NSAID's and corticosteroids act principally by blocking the effect or secretion of these mediators but do nothing to modify the immunologic basis of the disease. On the other hand, cytotoxic agents such as cyclophosphamide, act in such a nonspecific fashion that both the normal and autoimmune responses are shut off. Indeed, patients treated with such nonspecific immunosuppressive agents are as likely to succumb from infection as they are from their autoimmune disease. Cyclosporin A which was approved by the US FDA in 1983 is currently the leading drug used to prevent rejection of transplanted organs. The drug acts by inhibiting the body's immune system from mobilizing its vast arsenal of natural protecting agents to reject the transplant's foreign protein. Though cyclosporin A is effective in fighting transplant rejection, it is nephrotoxic and is known to cause several undesirable side effects including kidney failure, abnormal liver function and gastrointestinal discomfort. Newer, safer drugs exhibiting less side effects are constantly being searched for in the field. The 23-membered tricyclo-macrolide immunosuppressant, tacrolimus, FR-900506, FK-506, ( 17-ally 1- 1 , 14-dihy droxy- 12- [2'-(4"-hydroxy-3 "-methoxy cy clohexy 1)- 1 '- methylvinyl]-23 ,25-dimethoxy- 13 , 19,21 ,27-tetramethyl- 11 ,28-dioxa-4- azatricyclo-[22.3.1.0 4 -9]-octacos-l 8-ene-2,3,10,16-tetraone) and related compounds which were isolated and characterized by Tanaka, Kuroda, and co-workers at Fujisawa Pharmaceutical Co. in Japan, see J. Am. Chem. Soc. 1987, 109, 5031, and U.S. Patent No. 4.894.366. issued January 16, 1990) have been shown to possess exceptional immunosuppressive activity. Fujisawa United States patents (U.S. Patent No. 4.929.611. issued May 29, 1990 and U.S. Patent No. 4.956.352. issued Sept. 11, 1990) disclose the use of FK-506-type compounds in treating resistance to transplantation. In particular, the compound FR- 900506 has been reported to be 100 times more effective than cyclosporin in the supression of in vitro immune systems (J. Antibiotics. 1987, 40, 1256). In addition, these compounds are reputed to possess topical activity in the treatment of inflammatory and hyperproliferative skin diseases and cutaneous manifestations of immunologically-mediated illnesses (EPO Pub. No. 0.315.978). The compound FK-506 and related compounds further have been suggested to be useful in the treatment of obstructive airways disease, particularly asthma (PCT Publication WO 90/14826). male pattern alopecia or alopecia senilis (EPO Publication No. 0.423.714). rheumatoid arthitis (C. Arita, et al., Clincial exp. Immunol.. 1990, 82, 456-461; N. Inamura, et al., Clin. Immunol. Immunopathol.. 1988, 46, 82-90), recent-onset diabetes (N. Murase, et al., Diabetes. 1990, 39, 1584-86; N. Murase, et al, Lancet. 1990, 336, 373-74), posterior uveitis (H. Kawashima, Invest. Ophthalmol. Vis. Sci.. 1988, 29, 1265-71), hepatic injury associated with ischemia (M. Sakr, et al., Life Sci.. 1990, 47, 687-91) allergic encephalomyelitis (K, Deguchi, et al, Brain Nerve. 1990, 42, 391-97), glomerulonephritis (J. McCauley, et al, Lancet. 1990, 335. 674), systemic lupus erythematosus (K. Takabayashi, et al., Clin. Immunol, hrnmunopathol.. 1989, 51,, 110-117) multidrug resistance (M. Naito, et al. Cancer Chemother. Pharmacol.. 1992, 29, 195-200), iiiflammation of mucosa and blood vessels (PCT Publication WO 92/17754). cytomegalovirus infection (UK Publication GB 2.247.620A). and idiopathic thrombocytopenic purpura and Basedow's disease (PCT Publication WO 91/19495). Baldness or alopecia, in addition to male pattern alopecia, female pattern alopecia, and alopecia senilis, includes alopecia areta, and further, diseases accompanied by basic skin lesions such as cicatrix or infectious tumors, or accompanied by systemic disorders, for examples, an internal secretion abnormality or nutritional disorder. In regard to alopecia areata, it is considered that an autoimmune phenomenon participates therein, and therefore, the administration of a substance having an immunosuppressive action can have therapeutical effect on alopecia areata. The causes of human pattern alopecia (also called "androgenic alopecia") and alopecia senilis are considered to be: an activation of male hormones at organs such as hair roots and the sebum gland; a lowering in the amount of blood reaching the hair follicles; a scalp abnormality caused by an excessive secretion of sebum, a formation or peroxides, or a propagation of bacteria; genetic; causes; and aging. The compound minoxidil (6-amino-l,2-dihydro-l-hydroxy- 2-imino-4-piperidinopyrimidine) was approved by the FDA for the treatment of male pattern baldness in August 1988. Minoxidil was also approved by the FDA for the treatment of female androgenetic alopecia on August 13, 1991. The preparation of minoxidil is described in U.S. Patent Nos. 3.382.247. 3.644.364 and 4.098.791. Upjohn United States Patents (U.S. Patent Nos. 4.139.619 and 4.596.812) discloses the use of minoxidil in the topical treatment of human baldness. Similarly, an Upjohn United States Patent (U.S. Patent No. 5.026.691) discloses the use of minoxidil and an antiinflammatory agent for the treatment of patterned male and female alopecia. Japanese patent Kokai 61-260010 states that topical minoxidil formulations containing other specified agents may be prepared. An Upjohn WIPO patent application (PCT Publication No. WO 92/09259) discloses a method and composition for promoting hair growth in mammals comprising the administration of a potassium channel opener and an androgen receptor blocker. A University of Miami WCPO patent application (PCT Publication No. WO 92/12703) discloser a method of stimulating hair growth comprising the topical application of a phospholipid. Merck United States Patent 4,760,071 discloses the 5 - reductase inhibitor 17β-(N-tert-butylcarbamoyl)-4-aza-5oc-androst-l-en- 3-one. Harris, et al., (Proc. Natl. Acad. Sci.

B. Preparation of Compounds Within the Scope of the Present Invention The starting materials for the preparation of the compounds of this invention are represented by Formula II: π wherein: Q is hydrogen or methyl; W is O or (H, OH); R3 is hydrogen, hydroxy, or C1-C6 alkoxy; R4 is hydrogen, or R3 and R4 taken together form a double bond; R-5 is methyl, ethyl, propyl or allyl; and n is 1 or 2. The production and characterization of compounds of Formula II is well known in the literature (see U.S. Patent No. 4.894.366 issued January 16, 1990; U.S. Patent No. 4.929.611 issued May 29, 1990; U.S. Patent No. 3.244.592 issued April 15, 1966; EPO Publication No. 0.323.042: EPO Publication No. 0.356.399: PBJ Disclosure 63-17884: J. Am. Chem. Soc. 1987, 109, 5031; and J. Antibiotics. 1987, 40, 1249). Both biological fermentation and synthetic processes may be found. A synthetic route to compounds of Formula II can involve modifications of a route described in J. Am. Chem. Soc. 1989, 111. 1157. Biological fermentation followed by synthetic modification is presently favored in the art as the method to produce compounds of Formula H Organisms belonging to the genus Streptomyces such as Streptomvces tsukubaensis. No. 9993 and Streptomyces hygroscopicus. No. 7238 placed in an aqueous nutrient medium will produce desired compounds in isolable amounts. The nutrient medium contains sources of assimilable carbon and nitrogen, preferably under aerobic conditions.

A lyophilized sample of the isolated Streptomyces tsukubaensis. No. 9993 was deposited with the Fermentation Research Institute, Agency of Industrial Science and Technology (No. 1-3, Higashi 1-chome, Yatabemachi Tsukuba-gun, Ibaraki Prefecture, Japan) under the deposit number of FERM P-7886 (deposit date: October 5th, 1984), and then converted to Budapest Treaty route of the same depository on October 19, 1985 under the new deposit number of FERM BP-927. Using the four compounds produced in fermentation above, the remaining compounds of Formula II may be easily produced. The allyl of R-5 may be conveniently reduced to propyl by well known methods, for example as described in U.S. Patent No. 4.894.366. The hydroxy of R3 may be protected by well known methods, for example as disclosed in EPO Publication No. 0.323.042. Likewise, the hydroxy at C- 4" may also be protected. In addition, the hydroxy of R3 may be reduced to a hydrogen or eliminated to form a double bond with R4 (by methods disclosed in U.S. Patent No. 4.894.366 or EPO Publication No. 0.323.042 or EPO Publication No. 0.413.532 .

The methyl of Q as produced may be replaced with hydrogen or demethylated and subsequently protected as desired, if necessary. This demethylation of compounds wherein Q is methyl may be carried out in a fermentation reaction using the compounds of Formula II as a feedstock.

Alternatively, the triarylbismuth(V) reagent can be prepared by treatment of a triarylbismuthine with a suitable oxidant such as peracetic acid, iodobenzene diacetate, bis(trifluoroacetoxy)iodobenzene and the like in an inert solvent such as methylene chloride, chloroform, benzene, toluene and the like. The triarylbismuth(V) reagent can be used without purification or can be purified by silica gel chromatography. Triarylbismuthines may be prepared by the reaction of an appropriate aryl Grignard reagent with bismuth trichloride in an inert organic solvent such as tetrahydrofuran, diethyl ether, or 1 ,4-dioxane, or mixtures thereof, at or near room temperature for a period of 1 to 48 hours. General procedures for the preparation and use of triaryl bismuth reagents may be found in Barton, D.H.E., et al, J. Chem. Soc. Chem. Commun.. 1986, 65 and references cited therein. Reaction Scheme B: Similarly, as shown in Reaction Scheme B, a solution of the 3",4"-dihydroxy macrolide is treated with a triarylbismuth diacetate reagent as described in Reaction Scheme A, to give a mixture of the 3"- hydroxy-4"-0-aryl macrolide, the 3"-0-aryl-4"-hydroxy macrolide, and the 3",4"-di-0-aryl macrolide. At this stage, a solution of 3"-hydroxy-4"- O-aryl macrolide, or 3"-0-aryl-4"-hydroxy macrolide can be treated with a different triarylbismuth diacetate reagent (prepared immediately prior to use by procedures analogous to those disclosed above), to give 3"-0-aryl- 4"-0-aryl macrolides. Reaction Scheme C: As shown in Reaction Scheme C the 14-hydroxy group of a macrolide (wherein R , R2, R5, and n are as defined above) may be eliminated by treatment with p-toluenesulfonic acid, benzenesulfonic acid, methanesulfonic acid, -nitrobenzenesulfonic acid, -bromobenze- nesulfonic acid, p-chlorobenzenesulfonic acid, or p-methoxybenzene- sulfonic acid, or mixtures thereof, in an inert organic solvent such as benzene, or toluene or the like at a temperature of 40°C to solvent reflux temperature, preferably 60°C, for about 0.5 to 6 hours, or a sufficient period of time to eliminate the 14-hy droxy group. Neutralization with an aqueous solution of a weak base such as aqueous saturated sodium bicarbonate gives the 14,15-dehydro macrolide. The 14-hydroxy group may also be eliminated by activation followed by basic elimination, as described in U.S. Patent No. 4.894.366. Reaction Scheme D: As shown in Reaction Scheme D the macrolide (wherein Rla and/or R-^a is alkenyl, substituted alkenyl, alkynyl or substituted alkynyl and wherein R^ a is hydroxy or Cl-6 alkoxy, R^ a is hydrogen, or R3 a and R^a taken together form a double bond) is reduced under an atmosphere of hydrogen in the presence of a noble metal catalyst, such as rhodium on carbon catalyst or rhodium on alumina catalyst, at a pressure of atmospheric pressure to 40 psig, at or near room temperature in an organic solvent such as ethyl acetate or ethanol for about 1 to 24 hours, or until the requisite amount of hydrogen is absorbed to reduce the olefin and give the reduced macrolide. By changing the sequence of synthetic steps, all possible variations of substitution can be achieved. For example, the C-14 hydroxy group may be eliminated and the resultant double bond reduced prior to the introduction of alkenyl or alkynyl substituents at C-3" and/or C-4". Reaction Scheme E: As shown in Reaction Scheme E, a solution of the 4"- hy droxy 3 "-methoxy macrolide in an inert organic solvent such as methylene chloride, chloroform, pentane, hexane, cyclohexane, heptane or the like or mixtures thereof is treated with an alkyl, alkenyl or alkynyl trichloroacetimidate reagent (prepared by the reaction of an appropriate sodium alkoxide with trichloroacetonitrile, such as described by Wessel, H.P., Iversen, T., Bundle, D.R., J. Chem. Soc. Perkin Trans. 1. 1985, 2247) in the presence of a mild acid catalyst such as trifluoromethanesulfonic acid, p-toluenesulfonic acid, methanesulfonic acid, benzenesulfonic acid, p-nitrobenzenesulfonic acid, p- bromobenzenesulfonic acid, p-chlorobenzenesulfonic acid, or p- methoxybenzenesulfonic acid, or mixtures thereof at a temperature of 20- 50°C, preferably room temperature, for a period of one hour to seven days, preferably one day, to give the 4"-0-alkyl, -alkenyl or -alkynyl 3"- methoxy macrolide. Reaction Scheme F: Similarly, as shown in Reaction Scheme F, (wherein R = Rl = R2) a solution of the 3",4"-dihydroxy macrolide in an inert organic solvent such as methylene chloride, chloroform, pentane, hexane, cyclohexane, heptane or the like or mixtures thereof is treated with an alkyl, alkenyl, or alkynyl trichloroacetimidate (prepared by the reaction of an appropriate sodium alkoxide with trichloroacetonitrile, such as described by Wessel, H.P., Iversen, T., Bundle, D.R., J. Chem. Soc. Perkin Trans. I. 1985, 2247) in the presence of a mild acid catalyst such as trifluoromethanesulfonic acid, p-toluenesulfonic acid, methanesulfonic acid, benzenesulfonic acid, p-nitrobenzenesulfonic acid, p-bromobenze- nesulfonic acid, p-chlorobenzenesulfonic acid, or p-methoxybenzene- sulfonic acid, or mixtures thereof of at a temperature of 20-50°C, preferably 40°C, for a period of one hour to seven days, preferably 6 hours, to give a mixture of the 3"-0-alkyl, -alkenyl or -alkynyl 4"- hydroxy macrolide, the 3 "-hydroxy 4"-0-alkyl, -alkenyl or -alkynyl macrolide and the 3",4"-di-0-alkyl,-alkenyl or -alkynyl macrolide. Reaction Scheme G: The procedures described in Reaction Schemes C and D may optionally be conducted following the procedures of Reaction Scheme E or F. Altematively, the procedures described in Reaction Scheme G may be performed. In Reaction Scheme G the macrolide (wherein Rla and/or R2a is alkenyl, substituted alkenyl, alkynyl or substituted alkynyl and wherein R3a is hydroxy or Cl-6 alkoxy, R^ a is hydrogen, or R*^ a and R4a taken together form a double bond) is reduced with tri-n-butyltin hydride in the presence of tetrakis-(triphenylphosphine)palladium(0) catalyst and acetic acid in an organic solvent such as toluene or tetrahydrofuran at or near room temperature for about 2 to 10 hours to give the reduced macrolide. The procedures described in Reaction Scheme F may be conducted on the mono-substituted products of Reaction Scheme B (and visa versa) to obtain the mixed disubstituted compounds. In fact, within Reaction Schemes B and F, treatment of the mono-substituted product with a different reagent will afford the mixed disubstituted compounds. Reaction Scheme H: Protection of the C-3", C-4" and/or the C-14 hydroxy group may be accomplished by methods known in the prior art for compounds of Formula II such as by treatment with: 2,6-lutidine and triisopropylsilyl trifluoromethanesulfonate in a solution of methylene chloride; 2,6- lutidine and t-butyldimethylsilyl trifluoromethanesulfonate in a solution of methylene chloride; pyridine and acetic anhydride in a solution of methylene chloride; pyridine and benzoyl chloride in a solution of methylene chloride; pyridine and p-nitrobenzoyl chloride in a solution of methylene chloride; imidazole and t-butyldiphenylsilyl chloride in a solution of methylene chloride; and the like. For example, as shown in Reaction Scheme H, the C-4", 14-dihy droxy C-3"-methoxy macrolide (or the C-3", 4", 14-trihydroxy macrolide) may be protected at C-14 as the t- butyldimethylsilyl ether by treatment with t-butyldimethylsilyl trifluoromethanesulfonate in methylene chloride to give the C-4",3"-di- O-TBDMS macrolide (or the C-3",4", 14-tri-O-TBDMS macrolide). Treatment with toluenesulfonic acid in methanol results in selective removal of the C-4" silyl ether (and C-3" silyl ether, if present) to give the C-14-0-TBDMS macrolide. Reaction Scheme I: As shown in Reaction Scheme I, the 4"-hydroxy-3"-R2θ- macrolide or alternatively the 3"-hydroxy-4"-Rlθ-macrolide (not depicted) (wherein R- is protected hydroxy or hydrogen) may be reacted with an alkenyl trichloroacetimidate (wherein Rl is C3-IO alkenyl) under conditions described in Reaction Scheme F to give the C-4"-0-alkenyl macrolide. Treatment with a stochiometric amount of osmium tetraoxide in an inert organic solvent, such as diethyl ether or tetrahydrofuran, in the presence of an amine base, such as pyridine or 4-methylmorpholine N- oxide, at or near room temperature gives the corresponding glycol (wherein A is Cl-8 alkyl). Treatment of the glycol with sodium metaperiodate in a solution of tetrahydrofuran/water gives the aldehyde. Alternatively, the alkenyl macrolide may be treated with sodium metaperiodate in the presence of a catalytic amount of osmium tetraoxide in an organic solvent to give the aldehyde directly. The aldehyde can be further oxidized to the carboxylic acid by treatment with sodium chlorite in buffered, aqueous tert-butanol. Reaction Scheme J: A variety of compounds may be prepared from the corresponding aldehyde as illustrated in Reaction Scheme J. The aldehyde may be reacted with a primary or secondary amine (wherein R^ and R7 are as defined above) in an organic solvent such as tetrahydro¬ furan to give an imine which is reduced in situ with a hydride reducing agent, such as potassium triphenyl borohydride or sodium cyanoboro- hydride, to give the macrolide bearing an amino alkoxy functionality at C-4". The aldehyde may also be reduced to the corresponding alcohol by treatment with a hydride reducing agent, such as potassium triphenyl borohydride or sodium cyanoborohydride in an organic solvent such as tetrahydrofuran. The alcohol may be further modified by utilizing the methods of Reaction Scheme B (wherein Rl a is unsubstituted or substituted phenyl, naphthyl or biphenyl) or Reaction Scheme F (wherein R b is unsubstituted or substituted alkyl, alkenyl or alkynyl). The procedures described in Reaction Scheme J are readily applicable to the preparation of compounds bearing analogous functionality at C-3". Reaction Scheme K: Amide derivatives may be prepared from the carboxylic acid as illustrated in Reaction Scheme K. The carboxylic acid may be coupled with a primary or secondary amine, HNR6R7 (wherein R6 and/or R^ are as defined) by any of the peptide coupling methods commonly used in the art, such as with BOP reagent, DCC/HOBT, or EDC/HOBT. Reaction Scheme L: Hydroxy and keto derivatives may be prepared from the corresponding aldehyde as illustrated in Reaction Scheme L. The aldehyde is reacted with a nucleophilic organometallic reagent such as a Grignard reagent, an organolithium reagent, or an organocerium reagent in an organic solvent such as methylene chloride or tetrahydrofuran to give the substituted hydroxy compound. Removal of hydroxy protecting groups at other positions of the macrolide (if necessary) gives the macrolide bearing a substituted hydroxy alkoxy functionality at C-4". The alcohol may also be oxidized to the corresponding ketone by well known methods, such as with 4-methylmorpholine-N-oxide in the presence of tetrapropylammonium perruthenate catalyst under dehydrative conditions. Removal of hydroxy protecting groups (if necessary) gives the macrolide bearing a substituted keto alkoxy functionality at C-4". The procedures described in Reaction Scheme L are readily applicable to the preparation of compounds bearing analogous functionality at C-3". Reaction Scheme M: Hydroxy macrolides (wherein Rl, R2, and/or R3 bear a hydroxy group) may be further derivatized by alkylation, acylation or phosphorylation to give ether, ester or phosphate derivatives (wherein Rl, R2 and/or R3 bear an -ORl 1 as defined above) by procedures well known to the practitioner of the art. Reaction Scheme N: As illustrated in Scheme N, the hydroxy macrolide may be derivatized by treatment with a substituted alpha-diazoketone in an inert organic solvent such as methylene chloride in the presence of a catalyst such as rhodium acetate to provide the corresponding ether adduct. The ketone functionality of the appended ether may be selctively reduced in an inert organic solvent such as diethyl ether or tetrahydrofuran at -78°C by treatment with a reducing agent, such as L-Selectride, potassium triphenlyborohydride, diisobutyl aluminum hydride or lithium triethylborohydride. Reaction Scheme O: Alternatively, as shown in Scheme O, treatment of the hydroxy macrolide with a substituted 2-diazoacetophenone in an inert organic solvent such as methylene chloride with a Lewis acid catalyst such as boron trifluoride etherate provides the corresponding ether adduct. The object compounds of Formula I obtained according to the reactions as explained above can be isolated and purified in a conventional manner, for example, extraction, precipitation, fractional crystallization, recrystallization, chromatography, and the like. It is to be noted that in the aforementioned reactions and the post-treatment of the reaction mixture therein, the stereoisomer(s) of starting and object compounds due to asymmetric carbon atom(s) or double bond(s) of the object compounds of Formula I may occasionally be transformed into the other stereoisomer(s), and such cases are also included within the scope of the present invention. In the present invention, compounds with asymmetric centers may occur as racemates, as diastereomeric mixtures and as individual diastereomers, with all isomeric forms of the compounds being included in the present invention.

These compounds possess pharmacological activity such as immunosuppressive activity, antimicrobial activity, and the like, and therefore are useful for the treatment and prevention of the resistance to transplantation or transplantation rejection of organs or tissues (such as heart, kidney, liver, lung, bone marrow, cornea, pancreas, intestinum tenue, limb, muscle, nervus, medulla ossium, duodenum, small-bowel, medulla ossium, skin, pancreatic islet-cell, etc. including xeno transplantation), graft-versus- host diseases by medulla ossium transplantation, autoimmune diseases such as rheumatoid arthritis, systemic lupus erythematosis, nephrotic syndrome lupus, Hashimoto's thyroiditis, multiple sclerosis, myasthenia gravis, type I diabetes mellitus, type II adult onset diabetes, uveitis, nephrotic syndrome, steroid-dependent and steroid-resistant nephrosis, Palmo-planter pustulosis, allergic encephalomyehtis, glomerulonephritis, etc., and infectious diseases caused by pathogenic microorganisms. The compounds of Formula I are also useful for treating inflammatory, proliferative and hyperproliferative skin diseases and cutaneous manifestations of immunologically-mediated illnesses such as: psoriasis, psoriatic arthritis, atopical dermatitis, contact dermatitis and further eczematous dermatitises, seborrhoeic dermatitis, Lichen planus, Pemphigus, bullous Pemphigoid, Epidermolysis bullosa, urticaria, angioedemas, vasculitides, erythemas, cutaneous eosinophilias, acne Alopecia areata, eosinophilic fasciitis, and atherosclerosis. More particularly, the compounds of Formula I are useful in hair revitalizing, such as in the treatment of male or female pattern alopecia or alopecia senilis, by providing epilation prevention, hair germination, and/or a promotion of hair generation and hair growth. The compounds of Formula I are further useful in the treatment of respiratory diseases, for example sarcoidosis, fibroid lung, idiopathic interstitial pneumonia, and reversible obstructive airways disease, including conditions such as asthma, including bronchial asthma, allergic asthma, intrinsic asthma, extrinsic asthma and dust asthma, particularly chronic or inveterate asthma (for example late asthma and airway hyperreponsiveness), bronchitis and the like. The compounds of Formula I may also be useful for treating hepatic injury associated with ischemia. The compounds of the invention are also indicated in certain eye diseases such as keratoconjunctivitis, vernal conjunctivitis, uveitis associated with Behcet's disease, keratitis, herpetic keratitis, conical cornea, dystorphia epithelialis corneae, comeal leukoma, ocular pemphigus, Mooren's ulcer, Scleritis, Graves' ophthalmopathy, severe intraocular inflammation, and the like. The compounds of Formula I are also useful for treating multidrug resistance of tumor cells, (i.e. enhancing the activity and/or sensitivity of chemotherapeutic agents), preventing or treating inflammation of mucosa or blood vessels (such as leukotriene B4- mediated diseases, gastric ulcers, vascular damage caused by ischemic diseases and thrombosis, ischemic bowel disease, inflammatory bowel disease (e.g., Crohn's disease and ulcerative colitis) necrotizing enterocolitis), or intestinal lesions associated with thermal bums, cytomegalovirus infection, particularly HCMV infection. Further, the compounds of Formula I are also useful for treating or preventing renal diseases including interstitial nephritis, Goodpasture's syndrome, hemolytic-uremic syndrome and diabetic nephropathy; nervous diseases selected from multiple myositis, Guillain- Barre syndrome, Meniere's disease and radiculopathy; endocrine diseases including hyperthyroidism and Basedow's disease; hematic diseases including pure red cell aplasia, aplastic anemia, hypoplastic anemia, idiopathic thrombocytopenic purpura, autoimmune hemolytic anemia, agranulocytosis and anerythroplasia; bone diseases including osteoporosis; respiratory diseases including sarcoidosis, fibroid lung and idiopathic interstitial pneumonia; skin diseases including dermato- myositis, leukoderma vulgaris, ichthyosis vulgaris, photoallergic sensitivity and cutaneous T cell lymphoma; circulatory diseases including arteriosclerosis, aortitis syndrome, polyarteritis nodosa and myocardosis; collagen including scleroderma, Wegener's granuloma and Sjogren's syndrome; adiposis; eosinophilic fasciitis; periodontal disease; nephrotic syndrome; hemolytic-uremic syndrome; and muscular dystrophy. Further, the compounds of the invention are indicated in the treatment of diseases including intestinal inflammations/allergies such as Coeliac disease, proctitis, eosinophilic gastroenteritis, mastocytosis, Crohn's disease and ulcerative colitis; and food related allergic diseases which have symptomatic manifestation remote from the gastrointestinal tract, for example migraine, rhinitis and eczema. The compounds of the invention also have liver regenerating activity and/or activity in stimulating hypertrophy and hyperplasia of hepatocytes. Therefore, they are useful for the treatment and prevention of hepatic diseases such as immunogenic diseases (e.g. chronic autoimmune liver diseases including autoimmune hepatitis, primary biliary cirrhosis and sclerosing cholangitis), partial liver resection, acute liver necrosis (e.g. necrosis caused by toxins, viral hepatitis, shock or anoxia), B-virus hepatitis, non-A/non-B hepatitis and cirrhosis. The compounds of the invention are also indicated for use as antimicrobial agents, and thus may be used in the treatment of diseases caused by pathogenic microorganisms and the like. The compounds of Formula I may also be useful in the prevention or treatment of immunodepression (such as AIDS, HIV infection, cancer, senile dementia, trauma (including wound healing, surgery and shock), chronic bacterial infection and certain central nervous system disorders), overdosages or toxicity of such immunosuppressive compounds, and as an adjunct to the administration of an antigen in vaccination. The pharmaceutical compositions of this invention can be used in the form of a pharmaceutical preparation, for example, in solid, semisolid or liquid form, which contains one or more of the compounds of the present invention, as an active ingredient, in admixture with an organic or inorganic carrier or excipient suitable for external, enteral or parenteral applications. The active ingredient may be compounded, for example, with the usual non-toxic, pharmaceutically acceptable carriers for tablets, pellets, capsules, suppositories, solutions, emulsions, suspensions, and any other form suitable for use. The carriers which can be used are water, glucose, lactose, gum acacia, gelatin, mannitol, starch paste, magnesium trisilicate, talc, corn starch, keratin, colloidal silica, potato starch, urea and other carriers suitable for use in manufacturing preparations, in solid, semisolid, or liquid form, and in addition auxiliary, stabilizing, thickening and coloring agents and perfumes may be used. For example, the compounds of Formula I may be utilized with hydroxypropyl methylcellulose essentially as described in U.S Patent No. 4.916.138. issued April 10, 1990, or with a surfactant essentially as described in EPO Publication 0.428.169. Oral dosage forms may be prepared essentially as described by T. Hondo, et al, Transplantation Proceedings. 1987, XIX. Supp. 6, 17-22. Dosage forms for external application may be prepared essentially as described in EPO Publication 0.423.714. The active object compound is included in the pharmaceutical composition in an amount sufficient to produce the desired effect upon the process or condition of diseases. For the treatment of these conditions and diseases caused by immmunoirregularity a compound of Formula I may be administered orally, topically, parenterally, by inhalation spray or rectally in dosage unit formulations containing conventional non-toxic pharmaceutically acceptable carriers, adjuvants and vehicles. The term parenteral as used herein includes subcutaneous injections, intravenous, intramuscular, intrasternal injection or infusion techniques. For the treatment of reversible obstructive airways disease, it is preferable that the compound of Formula I be administered by inhalation to the lung, especially in the form of a powder. For modifying the activity and/or toxicity of FK-506-type immunosuppressants, a compound of Formula I may be administered prior to, in conjuction with or subsequent to the administration of an FK- 506-type of a compound. The compounds of Formula I may optionally be employed in co-therapy with anti-proliferative agents. Particularly preferred is co- therapy with an antiproliferative agent selected from the group consisting of azathioprine (AZA), brequinar sodium, deoxyspergualin (DSG), mizaribine, mycophenohc acid morpholino ester (RS-61443), cyclosporin and rapamycin. The compounds of Formula I may also be employed in conjunction with (or in a pharmaceutical composition additionally comprising): ( 1 ) a 5 α-reductase inhibitor, (2) a cyclosporin, (3) a potassium channel opener (such as minoxidil), or (4) a phospholipid. Such co-therapy is particularly useful in hair revitalizing, such as in the treatment of male pattern alopecia, female pattern alopecia, alopecia senilis or alopecia areata, by providing epilation prevention, hair germination, and/or a promotion of hair generation and hair growth. Such co-therapy is further useful in treating the hyperandrogenic conditions of androgenic alopecia, acne vulgaris, seborrhea, and female hirsutism. For co-therapy of these conditions and diseases a compound of Formula I may be administered in combination with prior to, concurrent to, or subsequent to the administration of other agent(s). For hair revitalizing the compound of Formula I may be administered topically or orally. Cyclosporin may be administered topically or orally. Although the 5α-reductase inhibitor or the potassium channel opener may be administered topically or orally, it is preferable that it be administered topically to the scalp. For unitary formulation, however, the preferred mode of administration is topically. It is especially preferred that the hair revitalizing composition of the present invention is administered by a percutaneous administration or by spraying onto the skin. Dosage levels of the compounds of the present invention are of the order from about 0.005 mg to about 50 mg per kilogram of body weight per day, preferably from about 0.1 mg to about 10 mg per kilogram of body weight per day, are useful in the treatment of the above-indicated conditions (from about 0.7 mg to about 3.5 mg per patient per day, assuming a 70 kg patient). In addition, the compounds of the present invention may be administered on an intermittent basis; i.e. at daily, semiweekly, weekly, semi-monthly or monthly intervals. The amount of active ingredient that may be combined with the carrier materials to produce a single dosage form will vary depending upon the host treated and the particular mode of administration. For example, a formulation intended for the oral administration of humans may contain from 0.5 mg to 5 gm of active agent compounded with an appropriate and convenient amount of carrier material which may vary from about 5 to about 95 percent of the total composition. Dosage unit forms will generally comprise from about 0.01 mg to about 500 mg, and preferably about 0.5 mg to about 100 mg of active ingredient. For external administration the compound of Formula I may be formulated within the range of, for example, 0.0001% to 60% by weight, preferably from 0.001 to 10% by weight, and most preferably from about 0.005 to 0.8% by weight. It will be understood, however, that the specific dose level for any particular patient will depend on a variety of factors including the activity of the specific compound employed, the age, body weight, general health, sex, diet, time of administration, route of administration, rate of excretion, drug combination and the severity of the particular disease undergoing therapy. The following examples are given for the purpose of illustrating the present invention and shall not be construed as being limitations on the scope or spirit of the instant invention.

Sample Preparation 5 The compounds to be assayed were dissolved in absolute ethanol at 1 mg/ml. 2. Assay Spleens from C57B1/6 mice were taken under sterile o conditions and gently dissociated in ice-cold RPMI 1640 culmre medium (GIBC), Grand Island, N. Y.) supplemented with 10% heat-inactivated fetal calf serum (GIBO)). Cells were pelleted by centrifugation at 1500 rpm for 8 minutes. Contaminating red cells were removed by treating the pellet with ammonium chloride lysing buffer (GIBO)) for 2 minutes at 4°C. Cold medium was added and cells were again centrifuged at 1500 rpm for 8 minutes. T lymphocytes were then isolated by separation of the cell suspension on nylon wool columns as follows: Nylon wool columns were prepared by packing approximately 4 grams of washed and dried nylon wool into 20 ml plastic syringes. The columns were sterilized by autoclaving at 25°F for 30 minutes. Nylon wool columns were wetted with warm (37°C) culture medium and rinsed with the same medium. Washed spleen cells resuspended in warm medium were slowly applied to the nylon wool. The columns were then incubated in an upright position at 37°C for 1 hour. Non-adherent T lymphocytes were eluted from the columns with warm culmre medium and the cell suspensions were spun as above. Purified T lymphocytes were resuspended at 2.5 x 10*5 cells/ml in complete culture medium composed of RPMI 1640 medium with 10% heat- inactivated fetal calf serum, 100 mM glutamine, 1 mM sodium pymvate, 2 x 10-5 M 2-mercaptoethanol and 50 μg/ml gentamycin. Ionomycin was added at 250 ng/ml and PMA at 10 ng/ml. The cell suspension was immediately distributed into 96 well flat-bottom microculture plates (Costar) at 200 μl/well. The various dilutions of the compound to be tested were then added in triplicate wells at 20 μl/well. The compound 17-allyl-l,14-dihydroxy-12-[2'-(4"-hydroxy-3"- methoxycyclohexyl)- 1 '-methy Ivinyl] -23 ,25-dimethoxy- 13 , 19,21 ,27- tetramethyl-l 1, 28-dioxa-4-azatricyclo[22.3.1.0 4 - ]octacos-l 8-ene- 2,3,10,16-tetraone was used as a standard. The culmre plates were then incubated at 37°C in a humidified atmosphere of 5% Cθ2-95% air for 44 hours. The proliferation of T lymphocytes was assessed by measurement of tritiated thymidine incorporation. After 44 hours of culturing, the cells were pulse-labelled with 2 μCi/well of tritiated thymidine (NEN, Cambridge, MA). After another 4 hours of incubation, cultures were harvested on glass fiber filters using a multiple sample harvester. Radioactivity of filter discs conesponding to individual wells was measured by standard liquid scintillation counting methods (Betacounter). Mean counts per minute of replicate wells were calculated and the results expressed as concentration of compound required to inhibit tritiated thymidine uptake of T-cells by 50%. A selection of compounds were tested according to the previous procedure. The title compounds of the following Examples had activity in inhibiting the proliferation of T-cells in the aforementioned assay: 1, 2A, 2B, 3, 4, 5, 6A, 6B, 7, 8A, 8B, 9, 10A, 10B, 11, 12A, 12B, 13, 14, 15A, 15B, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 43, 44, 45, 46A, 46B, 47B, 48A, 49A, 49B, 50A, 50B, 51A, 51B, 52, 53, 54A, 54B, 55, 56, 57, 58, 59, 60, 61, 64, 70, 73, 76, 77, 77B, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99, 100, 101, 102, 103, 104, 105, 106, 107, 108, 109, 110, 111, 112, 113, 114, 115, 116, 117, 118, 119, 120, 121, 122A, 122B, 123A, 123B, 124A, 124B, 125, 126A, 126B, 127 A, 127B, 128A, 128B, 129A, 129B, 130, 131, 132, 133, 134, 135, 136, 137, 138, 139, 140, 141, 142, 143, 144, 145, 146, 147, 148, 149, 150, 151, 152, 153, 154, 155, 156, & 157.
